We still have to pressure test it, so we'll see how it holds up.

The car is in the shop now and is awaiting the trail fit for the compounds. If it only knew what is coming..

And we ordered a bunch of parts (wastegate, BOV etc)from Sweden and the US, Hopefully they'll be here this week.

Cool stuff

And how did you do the merge between the intakebody and the runners?

Does gas/paint thinner not have any ill affects on the carbon fiber? Any specs on the rest of the car? Rad Build! BTW, this thread is showroom worthy if not project/resto worthy. May want to have a mod move it for ya?

[F20A2-T]

MAN THAT IS THE ONE!! How much would you need for one of those if it holds up to the pressure test? That is going to make BIG POWER! looks like surge tank intakes used on 1000hp supras. what are you using for the twins?

Let's hope it makes big power!!
For the compound twins we're going with a .60/.63 T3 for the HP and a GT35R for the LP.

Cool stuff
And how did you do the merge between the intakebody and the runners?

The CF is sandwiched between two aluminium plates which fit over the runners.
Only the inner plate is welded to the runners.

As far as i know the gas doesn't have an effect on the CF. But I would have to ask Stefan to be sure. I think we otherwise would end up with a very floppy intake
The Car (1982 240 Turbo) is completly stock at the moment. When the engine is finished, we'll turn our attention to the car. It'll get the full treatment for sure.


Thanks everyone for the positive reactions!! It sure makes us want to continue this build.
It will be slow going for the most of time. But we'll get there in the end.

why are u using a b21? because you just have it, have to (reglement of something), or want to?

It is easier to keep the original engine. Otherwise it would have to be re-registered.
A lot of guys don't do this, but you'd run the risk of having no insurance when you get in to an accident.
We just want to be on the safe side.

There is a B200K in the car now just for mock-up purposes.

Since I did change my engine I can tell you that you can go to the rdw and apply for uhmm.

In t Nederlands; voor ongeveer €50,- heb ik een omkeuring laten doen. Ik moest aantonen dat het nieuwe blok niet gestolen was en dat het goed ingebouwd was (maar was toch origneel volvo dus geen probleem). Ze hebben de auto ook opnieuw gewogen en de rembalans getest (niets gezegd over grotere remmen). Nu staat alles op kenteken en is het dus ook in orde met de verzekering. Dit kan in feite met alle auto's en alle motoren mits het chassis ouder is dan iets van 1998.

But the B21 is a nice and strong engine, so I like your choice. Great build so far!! Holland ftw

Injector fitting....




Next up...
Making a fuelrail. And a whole lot of other things

@ Turbosteen
Yes we could have it re-approved. But we'd like to stay with original engine.
Although we might have it re-approved for the "small" horsepower gain.

[MadDog_945]

Mh.. arent they sitting too deep in that pocket ? i would be concerned about drips who could occur around the edges due to fuel is sprayed against the wall?


/edit

did you just pinned up the pasticbags from your orders ? :D or do you have an endorsement with KLR ? IC many parts from him ;)

We'll do a spray pattern test first. Just to see how things work. We can open up the holes in the head if it wouldn't work.

KL-racing has sent us many parts already.... In the picture you see a box with their tape on it. Just a coincidence it was there when we took the picture.

Hmmm nice work. Loving the thread. Keep up the good work!

We doen ons best
We zitten in Noord-Limburg... In de buurt van Venlo.

Anywho....
Some updates from the ignition department
Our Holva (Honda/Volvo) ignition.





And our two little wastegate friends

Ok a little update from me... Pjotr has been posting on my behalf, thanks for that..

Last Saturday I finally got time to drill out the K-jet injector holes. It was kind of tricky opening those up as I wanted the new injectors to sit as deep as possible. The RC injectors also turned out to have a larger diameter compared to stock Honda injectors.

As you can see I also opened up the hole inside the intake port, this way I’m pretty sure the spray pattern isn’t compromised. (a spray test will have to confirm this)







Im still amazed to what glass bead does to aluminium, the thing looks brand new!

Anyway, I still need to clean the valves u little bit, the coating on the intake valves has been slightly damaged and I don’t want any hot spots bcs of this .

If all goes according to plan we will be able to bolt the head on next Wednesday.
Then ill also do a pressure test to make sure the intake manifold holds… (fingers crossed!!)

I still need to order an additional set of turbo flanges so we can start the whole piping campaign.

[F20A2-T]

Damn... You beat me to it :P

[MadDog_945]

glasbead is the **** !!

[740volvo]

That looks just like my dizzy setup.

[F20A2-T]

Well, the engine is completly built...
Next-up: Making the compounds....
And a whole lot of other stuff.....

I'll upload some pictures from the completed engine in a few days and hopefully some from our mock-up stages for the turbos

[DNAsEqUeNcE]

Maybe take down the valve guides to the head?

Awesome Build!

What do you use to make sure there is no residual glass beading in any oil/water passages? They will wreck the new engine very quickly if they are in there attached to the walls.

I'm curious about the injectors set directly in the head - isn't the heat soak going to be an issue? The K-Jet at least had phenolic spacers.

ive been running efi injectors directly into a k-jet head for 75 000km or so without issue. didnt modify the injector holes at all, mind you i didnt check the spray pattern either. i know people have put efi injectors into modified k-jet injector holders before, making them sit even higher, without issue.

[MadDog_945]

They get cooled by the fuel.. so.. should work?

[F20A2-T]

Sooo... We had some time to spend...
Mock-up of the turbo's and the 3" downpipe.
And i ran the ignition wires..

On the mock-up engine / parts-car





And on the engine.






Now let's get TIGgy with it...

[500dollar744ti]

****ing awesome, excellent work! keep it up..
